* Revert r128175.Andrew Trick2011-03-231-28/+11
| | | | | | | I'm backing this out for the second time. It was supposed to be fixed by r128164, but the mingw self-host must be defeating the fix. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128181 91177308-0d34-0410-b5e6-96231b3b80d8
* Reapply Eli's r127852 now that the pre-RA scheduler can spill EFLAGS.Andrew Trick2011-03-231-11/+28

* Add a target-specific branchless method for double-width relationalEli Friedman2011-03-181-11/+28
| | | | | | | | | | | | | comparisons on x86. Essentially, the way this works is that SUB+SBB sets the relevant flags the same way a double-width CMP would. This is a substantial improvement over the generic lowering in LLVM. The output is also shorter than the gcc-generated output; I haven't done any detailed benchmarking, though. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127852 91177308-0d34-0410-b5e6-96231b3b80d8

* For PR1319:Reid Spencer2007-04-161-3/+2
| | | | | | | | | Remove && from the end of the lines to prevent tests from throwing run lines into the background. Also, clean up places where the same command is run multiple times by using a temporary file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@36142 91177308-0d34-0410-b5e6-96231b3b80d8
